Red Sox Opening Day Ceremonies at Fenway Park to begin at 2:30 p.m. on Monday

"Calling All Kids" will provide a presence of children; More than 39,000 have joined Red Sox Kid Nation presented by Hood; Fans are urged to take the T or commuter rail and come early

The Red Sox will present their Opening Day Ceremonies before their 115th home season, and their 104th at Fenway Park, this Monday, April 13, starting at approximately 2:30 p.m. The team then plays the Washington Nationals at 3:05 p.m. This year marks the first time that the Nats have ever opposed the Red Sox in the home opener.

Before engaging in an interleague battle, the two teams will be introduced along the base lines, with participation from children. "Calling All Kids" is a season-long theme this year.

With Hanscom Air Force Base presenting the colors, a children's choir will perform the national anthem, punctuated by a fly-over of two F-16 fighter jets from the 158th Fighter Squadron from Burlington, Vermont's Air National Guard ("The Green Mountain Boys").

The Ceremonial First Pitch will pay tribute to a high point of an otherwise long, cold, and snowy winter, followed by the declaration to "Play Ball," presented by Target.

Fenway Park gates will open two hours before the game on Monday. For the rest of the season, gates open 1 1/2 hours before game time. Season ticket holders and Red Sox Nation members may enter at Gate C 2 1/2 hours before each game.

To comply with Major League Baseball Stadium Operations Practices for the 2015 season, and to enhance security and expedite screenings at the gates, fans will walk through new metal detectors at every gate. Fans will remove cell phones, cameras, and other large metal objects before walking through the metal detectors. Fans do not need to remove smaller objects, such as wallets, coins, keys, jewelry, eyeglasses, shoes, and belts.

Children 14 and under are invited to enter via the new Gate K (for Kids) near Gate B, a gateway to the new Kids Concourse. From the 3rd through the 7th innings, the new Wally's Clubhouse will offer an in-game play area for children.

This year, the Red Sox waived the entry fee into their children's fan club. So far, more than 39,000 fans 14 and under have signed up to join Red Sox Kid Nation presented by Hood.

Inside the turnstiles, fans of all ages will have new menu options. On Yawkey Way, Aramark has invested in a fresh look for their concession stands and new menu items, including the new "Taste of Boston" stand which will feature neighborhood cuisine from 12 different local restaurants that will rotate throughout the season. The club worked with Mayor Martin J. Walsh's office to choose the small businesses that will be featured this season.

Nachos will be served in life-sized Red Sox helmets inside Gates C and E, and roast beef and turkey panini sandwiches will be available in both the left and right field concourses. Meatball Obsession, the official meatball of the Boston Red Sox, will debut a new stand in the Kids Concourse near Wally's Clubhouse with their popular turkey or beef meatballs served in a cup. And a new kids meal for $5 - available in the Kids Concourse - will feature a peanut butter and jelly sandwich, Goldfish, and a small juice.

The refurbished Budweiser Brew House in right field, operated by Aramark, will offer a host of new drink and food items in the newly expanded bar and lounge seating areas, including Bacon & Apple Salad, Truffle Parmesan Fries, Chorizo and Manchego Croquettes, Brew House Flatbread, Pastrami Sliders, Fish Tacos, and authentic Lobster Rolls. The Budweiser Brew House is now open to all ticketed patrons.

At all concession stands at Fenway Park, fans will have an opportunity to support the Red Sox Foundation through their new "It Makes Sense to Give 50 Cents" campaign. Aramark employees will take 50 cent donations from fans who wish to add that sum to their concession tab.

The 3rd Base Deck in the left field upper level concourse will now be known as the Ketel One Vodka 3rd Base Deck. The bar will feature Ketel One Vodka products and branding throughout.

The Red Sox urge fans to use public transportation to Fenway Park. In addition to taking the popular T to Kenmore Square, the commuter rail trains arrive at Yawkey Station, just 511 feet from the doorstep of Fenway Park. Yawkey Station is part of the commuter rail's Framingham/Worcester line, which runs from Worcester to South Station.

The last outbound commuter rail train from Yawkey Station departs at 11:36 p.m. on weekdays and 11:10 p.m. on weekends. Departure times for the last Yawkey Station train are subject to change based on the length of the game. These trains offer as many as 48 regularly scheduled stops every weekday.
